Chapter 5 Deployment CPU 21x-2BT02 with H1 / TCP/IP Manual VIPA CPU 21x
5-10 HB103E - Rev. 05/45
When the CPU 21x-2BT02 is first turned on the module has a predefined
initial Ethernet address.
This address is available from the label that has been attached to the side
of the module.
This Ethernet address is only used when the module is first turned on, to
calculate a unique IP address according to the following formula:
00 20 D5 80 2D 7D
Ethernet address
hex->dec
213.128.45.125
IP-address
VIPA-specific
Note!
A relationship between the Ethernet address and the IP address only exists
when the module is turned on for the first time.
You may always use the function CP-Init in WinNCS to assign a different
address.
Attention!
The original Ethernet address may not be restored since it is not possible
to perform an overall reset of the CP section.
